Round One of PennLive's Beer Brackets marches on with a matchup made to measure the true mettle of a beer fan: Pennsylvania classic Yuengling Lager vs. the Parrothead's preferred beverage -- other than a margarita, that is: Land Shark Lager.

Ask for a lager in Pennsylvania, and you will be passed this jewel from America's oldest brewing company. Yuengling was so popular with nominators that several of its brews stood a fighting chance at making a go of the bracket, but between the ones that made our competition -- the Lager and Porter -- which do you think will triumph?

Among the Beer Bracket nominees, one of the few Anheuser-Busch brands to stand out was Land Shark: house lager Jimmy Buffett's Margaritaville restaurants. Do you think such a corporate brew has no place in PennLive's Beer Brackets? Or do you want to stick up for the people's preference?
